This is our most popular Callbox with gate opening control, but it also has a keypad that enables authorized users with pre-assigned entry codes to activate the door or gate controller or door lock.

The illuminated keypad provides audible feedback on button presses. There are 502 possible codes for up to 500 users. One code is used for temporary purposes and it expires in a programmable 1 to 99 hours. The other remaining code is the master code used for programming. The codes are variable and can be between 3 to 8 digits.

The entry keypad with built-in relay and the callbox relay are each wired separately to the controller device.

The UHF XT Callbox with Keypad works with our other MURS radios and it provides long range, 2-way voice communication from the fixed location of the Callbox to any of your other MURS intercom units. It has a range of up to one mile or more with an optional external antenna.

This heavy duty outdoor intercom is designed for construction sites, golf courses, hotels/motels, airport parking lots, gated entrances, manufacturing, college campuses, hospitals, receiving docks, amusement parks, resorts, locked entrances, farms, ranches, warehouses, campgrounds, parking lots, delivery doors, and any other application that needs two way communication for safety or convenience.

There is no need for extensive wiring, trenching, remodeling, or installing dedicated phone lines with expensive monthly fees since the Callbox is completely wireless.

For simple installation, the Callbox is designed to operate on 6 D-cell batteries (alkaline or Ni-Cad rechargeable). An optional external power supply is also available.

The Callbox has two modes of power consumption. In Automatic Turn-Off the unit turns itself off after a programmed amount of inactivity (up to 4 minutes). It can only be turned on again by pressing its Call button on the Callbox. In this mode it cannot receive calls from other intercom or handheld radio units. It can only make calls and then other units can respond.

In Normal mode, the unit does not turn itself off and the Callbox can not only make calls, but receive them as well. This mode consumes the largest amount of power and should only be considered if an external source of power is available. If an external source of power is used, the internal batteries can be installed as a back-up against loss of

If you use this Callbox along with the UHF Commercial Intercom or the UHF J-V410 Two-Way Radio , the Callbox can be used to remotely control gates, magnetic door locks and other devices. The MURS Callbox has a single 1-Amp switch output that can be activated when the Callbox receives a unique 2-Tone encode signal that the UHF Commercial Intercom and MURS J-V410 can send.

A 2-Tone encode signal can also be used to activate the Listen-In feature of this Callbox, which lets you listen to what's happening around the Callbox for up to 30 seconds.

This Callbox has a switch output that can be used to open or close a gate, turn on a light, sound an alarm, or any application where remote control of an On/Off switch is required. The switch can be programmed to operate in several ways:

  • On/Off Code: The switch will close when a preprogrammed code is received, and open when it is received again. The switch will also open by itself when the Callbox's preprogrammed Automatic Turn Off feature is activated.
  • Switch On When Called: The switch closes when the callbox first receives the call and it remains on until its Talk button is pressed, or a programmable timer expires (1-255 seconds).
  • Switch On When Callbox In Use: The switch will close when the Callbox first sends or receives a call and remains closed until a preprogrammed timer expires.
  • Switch On When Active Includes Turn-Off Code: Switch closes when the Callbox sends or receives a call with the added ability to open the switch when the Callbox receives a preprogrammed code.
  • Momentary Close: Switch will close for 1-255 seconds when a preprogrammed code is received.
  • Alternate Open and Close: Switch will toggle between open and closed when it receives a preprogrammed code. The Callbox transmits a single beep when open and a double beep when closed.

This Callbox also has a Sensor Input that allows it to also operate as a motion, gate entry, tamper or vehicle detection device. It will send a tone alert when optional switch/sensor status changes. The Callbox will send a warning tone when a change in the Sensor Input is detected. The Sensor Input will respond to an OPEN or CLOSED switch.

The Listen In feature allows remote activation of the callbox's transmitter when a unique 2-Tone code is received. This enables you to listen in to the area around the callbox for a period of up to 30 seconds.

The Callbox is housed in a fiberglass enclosure with a stainless steel faceplate that includes tamper-resistant fasteners and a concealed antenna making it perfect to withstand harsh elements.
